The Design And Implementation Of The Data Central Environment Monitoring System Based On ZigBee

With the development of information technology, and now the level of information in various industries are constantly improving, information technology has also been strengthened. So, as the collective storage space of information devices, informational IT room is crucial for informationization building. IT room surveillance system is a key part for IT room building and responsible for the safety, stability and reliability. But a lot of IT room surveillance system lack structural diversity and scalability, even most IT room surveillance system also uses C/S model to build a monitoring platform, do not have remote access capabilities, which has can not reach the requirements from high speed improving informationization. According to the analysis to present situation of IT room surveillance system, this article fully considered bank IT room surveillance system requirements from reality and in-depth study of the data acquisition technology, ZigBee wireless sensor network technology and Web server technology, finished design and realization of informational IT room surveillance system.Divided surveillance system into 3 parts in whole structure for realizing:ZigBee wireless sensor network, IT room surveillance units, IT room surveillance platform. Functionally, the completion of the environmental parameters of the engine room and engine room equipment parameters of the acquisition, processing and analysis and storage capabilities and implements remote access IT room monitoring system.Compared and analyzed several kinds of short distance wireless communication technologies, combined project reality requirements for deciding to use ZigBee wireless sensor network to collect data. Then, researched ZigB-ee wireless sensor network structure and network protocol framework in detail. Completed sensor and ZigBee chip model selection firstly, designed ZigBee wireless sensor network hardware circuit which included ZigBee core module, node power module, serial port communication module, external storage module, debugging module and clock circuit. Based on Z-Stack protocol, programmed software and did network testing.For making sure the data transmit reliability, completed IT room surveillance units communication protocol design and realized system communication successfully. Based on B/S mode, constructed Web server on surveillance platform with data store function. Finally, through the monitoring system unit testing and integration testing. The system required functions have been achieved.
